Have you ever seen a ghost, care to share?

I believe i have had a few encounters with ghost. One being when i was little, staying at my grandparents, i came down the stairs and saw a ghost in her sun room. After about three seconds of standing there i ran back up the steps, i was quite frightened. The other times that i have seen a ghost, we were on vacation in Williamsburgh Virgina and we went on a ghost tour at night. Some of the houses we stopped at you could see figures in the windows, at least i could. So I took pictures and there it was a, a ghostly figure with a hooded cap on.
